This man showed how interaural level differences and interaural time differences lead to sound
 localization. He first mathematically described the instability of a denser fluid when placed above a less
 dense fluid, an instability co-named for Taylor. The viscosity and thermal diffusivity appear in the
 denominator of his namesake number, which is low when conduction occurs and high when convection
 occurs. For a circular aperture, 1.22 times the wavelength divided by the aperture's diameter yi

 man's criterion, which gives the minimal angular separation required to resolve two separate images.
 When the natural frequency of the atom is much greater than that of incident radiation, his namesake
 scattering occurs. For 10 points, name this physicist who won the 1904 Nobel Prize for the discovery of
 argon.
